The US Department of State describes the Model United Nation programs as
"Model UN Programs are a great way for students of all ages to learn about international relations and to gain a better sense of what a varied and fascinating world we live in. They also are a perfect "hands on" way to gain experience with basic skills -- such as communication, negotiation tactics, and conflict prevention -- that we all need in our day-to-day lives." http://www.state.gov/p/io/mdlun/
